Descriptions
A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed the malicious certificate or for the application to continue certificate verification despite failure to construct a path to a trusted issuer. An attacker can craft a malicious email address to overflow four attacker-controlled bytes on the stack. This buffer overflow could result in a crash (causing a denial of service) or potentially remote code execution. Many platforms implement stack overflow protections which would mitigate against the risk of remote code execution. The risk may be further mitigated based on stack layout for any given platform/compiler. Pre-announcements of CVE-2022-3602 described this issue as CRITICAL. Further analysis based on some of the mitigating factors described above have led this to be downgraded to HIGH. Users are still encouraged to upgrade to a new version as soon as possible. In a TLS client, this can be triggered by connecting to a malicious server. In a TLS server, this can be triggered if the server requests client authentication and a malicious client connects. Fixed in OpenSSL 3.0.7 (Affected 3.0.0,3.0.1,3.0.2,3.0.3,3.0.4,3.0.5,3.0.6).
Puede activarse una saturación del búfer en la verificación del certificado X.509, específicamente en la verificación de restricciones en el nombre. Tenga en cuenta que esto ocurre después de la verificación de la firma de la cadena de certificados y requiere que una CA haya firmado el certificado malicioso o que la aplicación continúe con la verificación del certificado a pesar de no poder construir una ruta a un emisor confiable. Un atacante puede crear una dirección de correo electrónico maliciosa para desbordar cuatro bytes en la pila de memoria controlados por el atacante. Este desbordamiento del búfer podría provocar un bloqueo (provocando una denegación de servicio) o una potencial ejecución remota de código. Muchas plataformas implementan protecciones contra el desbordamiento de la pila de memoria que mitigarían el riesgo de ejecución remota de código. El riesgo puede mitigarse, aún más, según el diseño de la pila de memoria para cualquier plataforma/compilador determinado. Los anuncios previos de CVE-2022-3602 describieron este problema como CRÍTICO. Un análisis más detallado basado en algunos de los factores mitigantes descritos anteriormente ha llevado a que esto se rebaje a ALTO. Aún se recomienda a los usuarios que actualicen a una nueva versión lo antes posible. En un cliente TLS, esto se puede desencadenar conectándose a un servidor malicioso. En un servidor TLS, esto se puede activar si el servidor solicita la autenticación del cliente y se conecta un cliente malintencionado. Corregido en OpenSSL 3.0.7 (Afectado 3.0.0,3.0.1,3.0.2,3.0.3,3.0.4,3.0.5,3.0.6).
A stack-based buffer overflow was found in the way OpenSSL processes X.509 certificates with a specially crafted email address field. This issue could cause a server or a client application compiled with OpenSSL to crash when trying to process the malicious certificate.
